Rack-Top Bags (trunks)

The ripstop fabric upper and rugged ballistic bottom panel are tough enough for cross-country treks, too.

From the people who brought you the Porteur House (Surly) comes a newer, svelter method of carrying things on your bike: the Petite Porteur House. Designed to fit both our 8 and 24 pack racks, the Petite Portuer House uses a system of six Velcro straps to securely snug it to the rack. The strap system is designed such that it will interface with many porteur-style racks with similar platform dimensions. The Petite Porteur House bag is made from durable 1050 Nylon Canvas with a polyurethane coating for protection from the elements. It uses a stiff insert in the bottom of the bag to give it shape and help keep wheel spray off your stuff. We also include four urethane coated, water-resistant nylon stuff sacks for an added layer of protection in each compartment. We've also included a handy light loop to help keep you visible and safe.
Surly's measuring stick says its 270 x 160 x 400mm so it has plenty of space for your ride necessities, tools, cool rocks, and whatever other bobbles you might feel inclined to bring with you.

The Porteur House bag has two accessory pockets on the front of the bag, each with a light loop to keep you visible and safe. Its main compartment is difficult to describe without using the word huge, and the roll-top closure keeps the rain out and your stuff in. The Porteur House also comes with a shoulder strap so you can take the bag off the bike and use it when you're at the Hallmark store shopping for your little figurines and keepsakes.
If you're the kind of person who likes accessories that make your bike infinitely more useful, the Porteur House is for you. With dimensions sitting at 400x270x450mm, fully extended, this bag will be a monolithic figurehead of two-wheeled practicality perched on the front of your bike. The strap system keeps it planted to your rack, and it's more than large enough to bring home the bacon – literally – so go to the store and get some bacon.
